Answer Details
A firm's average cost can decrease in the long-run due to increasing returns to scale. This means that as the firm increases its production, it experiences a decrease in its average cost. This can be due to various factors such as specialization, economies of scale, and better utilization of resources.
For example, a firm that produces 100 units of a product might have an average cost of $10 per unit. However, if it increases its production to 200 units, it might be able to reduce its average cost to $8 per unit. This could be due to the fact that the firm can take advantage of bulk discounts on raw materials, use more efficient production methods, and spread its fixed costs over a larger number of units.
Therefore, when a firm experiences increasing returns to scale, it can reduce its average cost in the long-run, which can lead to higher profits and a competitive advantage in the market.
